Got in about 150 hours, which is pretty good for me. It just got really tedious after a while, especially since the repetitive dialogues drag on. Even purchasing items in bulk takes time and there's no way to speed it up. As an example, whenever I wanted to buy a lot from Leif I literally had to buy 5 at a time, watch as the two figures exchanged money for seeds and then repeated it, like 10 times. Why couldn't I just buy 20 or 30 at once? This game just sucks up time for the sake of it. Basically after a while the flaws started to really stand out to me.
I was going to try to get all my fish but I burnt through about 200 baits and still couldn't get one of the pier fish. I got tired of it. I can't even do use the workbench to make 10 bait at a time. The game literally makes me do one at a time.
Online is also atrocious. There are so many interruptions and so many ways to slow down the process that it just wasn't fun. I did a lot of turnip selling online and tried to stick to lines that only allowed 2 - 3 people but it was still a slog. I ended up collecting a lot of bells in the end in the even my friends/siblings wanted to play. Figured I'd save them some of the hassle...
That being said, I still had some fun with it. Finding villagers, cleaning up the island, building up the museum, etc... Unfortunately it just lost its spark after a while.
I'll still poke in every now and then for the events but I think I'm pretty much done with it.
